METHOD OF REDUCING ROCK DAMAGE TO A TRAILER HAVING FENDERS

Abrégé anglais

A method of reducing rock damage to a trailer
having fenders is described. The method involves a
single step of securing deflector shields to opposed
sides of a trailer. Each deflector shield is angled
outwardly and rearwardly from one of the opposed sides of
the trailer to a peripheral edge of a fender. Each
deflector shield extends to a height substantially equal
to a top of the fender.

Description

- 21~729~
Title: A ~BTHOD OF RBDUCING ROC~ DAMAGB
TO A TR~ILBR HAVING FENDBR8
~C~GROUND OF THB INVBNTION
A number of trailer styles have fenders. These
fenders presently sustain damage from stones and other
road debris thrown up by the wheels of the tow vehicle.
A portion of the stones and road debris deflect off the
fenders and also cause damage to the sides of the
trailer.
A need exists for a device that will protect
the sides of trailers having fenders from damage
inflicted by stones thrown up from the road bed. The
present invention has as its object a method of reducing
rock damage to a trailer having fenders.
The invention in its general form will first be
described, and then its implementation in terms of
specific embodiments will be detailed with reference to
the drawings following hereafter. These embodiments are
intended to demonstrate the principle of the invention,
and the manner of its implementation. The invention in
its broadest and more specific forms will then be further
described, and defined, in each of the individual claims
which conclude this Specification.
8UMNARY OF T~E INVBNTION
According to one aspect of the present

2147295
_ 2
invention there is provided a method of reducing rock
damage to a trailer having fenders, comprising the step
of securing deflector shields to opposed sides of the
trailer forward of each fender. Each deflector shield is
angled outwardly and rearwardly from one of the opposed
sides of the trailer to a peripheral edge of a fender.
Each deflector shield is of a height at least as high as
a top of the fender.
With the method, as described above, the
deflector shield deflects stones and road debris that
would otherwise cause damage to the fenders and sides of
the trailer. The method also has a number of secondary
benefits. A more dynamic air flow is created in the area
of the fenders that contributes to trailer stability and
improves fuel economy. When driving in wet conditions,
the deflector shield deflects the spray of slush and
water away from the sides of the trailer.
According to another aspect of the present
invention there is provided an improvement in a trailer
having fenders which is comprised of deflector shields
secured to opposed sides of the trailer forward of each
finder. Each deflector shield is angled outwardly and
rearwardly from one of the opposed sides of the trailer
to a peripheral edge of a fender. Each deflector shield
is of a height at least as high as a top of the fender.
The foregoing summarizes the principal features

21~296
~_ 3
of the invention and some of its optional aspects. The
invention may be further understood by the description of
the preferred embodiments, in conjunction with the
drawings, which now follow.
BRIEF n~CPTPTION OF THF DRAWING8
These and other features of the invention will
become more apparent from the following description in
which reference is made to the appended drawings,
wherein:
Figure 1 is a top plan view of a trailer which
has been modified in accordance with the teachings of the
present method;
Figure 2 is a perspective view of one variant
of the deflector of the invention positioned on the side
of the trailer, with the fender omitted for clarity.
Figure 3 is a perspective view of another
variant of the deflector of the invention, positioned on
the side of the trailer with the fender omitted for
clarity.
D~TAILED DE8CRIPTION OF THE rK~R~D ~MBODINBNT
The preferred method of reducing rock damage to
a trailer having fenders will now be described with
reference to Figure 1.
Referring to Figure 1, there is illustrated a

21~729B
trailer 12 having fenders 14. The method involves a
single step of securing deflector shields 16 to opposed
sides 18 and 20 of trailer 12. Each deflector shield 16
has a first front end 22 and a second trailing end 24.
First end 22 of each deflector shield 16 is secured to
opposed sides 18 and 20 of trailer 12. Each deflector
shield 16 is angled outwardly and rearwardly from opposed
sides 18 and 20 of trailer 12 to a peripheral edge 26 of
one of fenders 14. Each deflector shield 16 extends to
a height substantially equal to a top 28 of one of
fenders 14. Deflector shields 16 serve to deflect stones
and road debris away from fenders 14 and sides 18 and 20
of trailer 12.
Referring to Figure 2, a first variant of the
deflecto-guard deflector shield 16 is shown in
perspective view positioned against the side 18 of a
trailer, forward of the fender which, for clarity, is
omitted from this view. In this variant the deflecting
surface 16a is supported by a sheet metal flange 36
attached between the trailer side 18 and to the trailing
end 24 and top edge 25 of the deflector surface 16a.
This flange 36 may be curved to extend over the top of
the deflector 16 to enclose the top of the deflecto-
guard; or it may contain an opening 38 to allow air to
pass therethrough. If a bottom (not shown) is provided
to the deflector 16, the opening 38 may serve to provide

2l4~296
access to the interior for storage. The front end 22 of
the deflecting surface 22 may be mounted directly to the
side of trailer 18.
The guard 16 and flange 36 may be made of sheet
material of, but not limited to, aluminum. Such sheet
material may be of steel, fibreglass or plastic,
whichever would be most suitable to meet conditions.
Referring to Figure 3, another variant
preferably made of aluminum is shown. In this variant
the front end 22 of the deflector surface 16a is again
fixed to the side of the trailer 18. A single, central
stiffening flange 30 extends outwardly from the trailer
side 18 as a support brace to hold deflector-guard to the
trailer side 18. Inwardly bent safety flanges 24a and
25a along the rear 24 and top edges 25 reduce the dangers
of exposed sharp edges.
It will be apparent to one skilled in the art
that modifications may be made to the embodiment
illustrated in the Figures without departing from the
spirit and scope of the invention s hereinafter defined
in the claims. In particular, it will be apparent that
although deflector shields 16 should extend at least as
high as top 28 of fenders 14, it can be extended higher
without adversely affecting the function of deflector
shields 16.
